Abstract
The invention relates to a synergistic sterilizing wettable powder and a preparation method thereof, which relates to the technical field of synergistic bactericide combination. The synergistic sterilizing wettable powder comprises active ingredients, a dispersing agent, a wetting agent and a filler, wherein the active ingredients comprise 1 to 30 percent of thifluzamide and 1 to 20 percent of hexaconazole based on the total mass of the wettable powder. The preparation method of the synergistic sterilizing wettable powder comprises the following steps of: adding the raw materials into an enamel stirring tank to mix uniformly; and pulverizing or grinding the raw materials through airflow to prepare a thifluzamide-containing and hexaconazole-containing wettable powder-shaped or suspending agent-shaped bactericide composition. Due to the compounding use of the thifluzamide and the hexaconazole, the synergistic sterilizing wettable powder has the advantages of low toxicity, low residues, wide sterilization spectrum and high long-term effectiveness and is an ideal high-efficiency and low-toxicity pesticide preparation variety for preventing and controlling various rice diseases.
Description
Technical field
The present invention relates to a kind of bactericide combination technique field with synergistic effect.
Background technology
The rice banded sclerotial blight disease is the main disease that hazard rice is produced, and realizes that the rice disease non-environmental pollution control is the developing direction and the objective of the struggle in agricultural plant protection field.In recent years, though country prohibites the agricultural chemicals that uses high poison and high residue on paddy rice, but for want of efficient disease control medicament in actual agricultural production process and use the phenomenon of persistent pesticide also comparatively general, therefore, the novel agrochemical of efficient, the low toxicity of research and development, low-residual is a pesticide research exploitation inevitable development trend.
Thifluzamide (thifluzamide) is a kind of novel thiazole acid amide fungicides, has strong interior conductivity and the long lasting effect of inhaling.Main effect is the acidohydrogenase that suppresses in the disease fungus tricarbonic acid cycle, causes thalline death.Thifluzamide is the succinate dehydrogenase inhibitor, because fluorine-containing, its its competitiveness in biochemical pathway is very strong, in case combine with regard to difficult recovery with substrate or enzyme.Thifluzamide all has activity to pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, nuclear cavity Pseudomonas, especially the fungus-caused disease of Basidiomycetes such as banded sclerotial blight, damping off etc. is had special efficacy.Thifluzamide does not have activity to the phycomycetes class, and is to the disease that is caused by leaf portion pathogen, bad as the cercospora brown spot of peanut, black spot effect.Single simultaneously thifluzamide list agent with high-load is higher in present use cost.
Own azoles alcohol (hexaconazole) belongs to azoles fungicide, sterol demethylation inhibitor, and the disease that fungi especially Basidiomycota and Ascomycota are caused has the protection and the therapeutic action of broad spectrum activity.Destroy and stop the biosynthesis of the cell membrane important composition composition ergosterol of germ, cause cell membrane not form, make germ death.Have interior suction, protection and therapeutic activity.Own azoles alcohol can be prevented and treated disease due to sac fungi, basidiomycetes and the imperfect fungus effectively, and especially disease that Basidiomycetes and Ascomycetes are caused such as powdery mildew, rust, scab, brown spot, anthracnose etc. have excellent protection and eradicant action.Rice sheath blight disease there is good preventive effect.The single agent of own azoles alcohol is to phytophthora, dry rot fungus weak effect.The time limit that is used to prevent and treat the main disease control of paddy rice simultaneously is longer, and the pesticide resistance of crop pest has had significant enhancing, and control efficiency descends.
Summary of the invention
The objective of the invention is at present efficient, wide spectrum disease control pesticidal preparations very lacks and existing agricultural chemicals list agent exists multiple deficiency, providing a kind of is a kind of bactericide with synergistic effect of product forms with the wetting powder.
The present invention includes active ingredient thifluzamide and own azoles alcohol, also comprise dispersant, wetting agent and filler, described thifluzamide accounts for 1～30% of wetting powder gross mass, and own azoles alcohol accounts for 1～20% of wetting powder gross mass.
Described dispersant accounts for 1～20% of wetting powder gross mass, and wetting agent accounts for 1～5% of wetting powder gross mass, and filler accounts for 25～96% of wetting powder gross mass.
The present invention adopts the use that is mixed of two kinds of low toxicity highly effective pesticides of thifluzamide and own azoles alcohol, it had both kept the thifluzamide advantage good to the control efficiency of rice banded sclerotial blight disease, and the advantage of the sterilization wide spectrum after thifluzamide and the composite use of own azoles alcohol, can overcome thifluzamide again the phycomycetes class there is not activity, the own azoles alcohol control efficiency existing shortcoming that descends year by year, reach the purpose of compound synergic, realize the target of the nuisanceless integrated control of corps diseases, reduction is to other biological toxicity, the minimizing chemical substance is residual crops, enlarge fungicidal spectrum, reduce cost, crops such as paddy rice are produced the requirement that higher effective and lower toxic pesticide is used to adapt to China.
Dispersant of the present invention adopts lignosulfonates, NNO, draws back a kind of or any two or three mixture of powder.Wherein, lignosulfonates are selected calcium lignosulfonate or sodium lignin sulfonate for use; Wetting agent adopts sodium alkyl benzene sulfonate or alkyl benzene calcium sulfonate.That filler adopts is silica-based, a kind of or mixture in the precipitated calcium carbonate, white carbon, silica-based employing potter's clay, kaolin and diatomite etc.
Another purpose of the present invention provides the preparation method of above product:
After earlier thifluzamide, own azoles alcohol, dispersant, wetting agent and filler fully being mixed in the enamel stirred tank, after airslide disintegrating mill pulverizing or sand mill grinding, mix again and make finished product; When feeding intake, described thifluzamide accounts for 1～30% of wetting powder gross mass, and own azoles alcohol accounts for 1～20% of wetting powder gross mass.
The present invention has many advantages such as production is simple, efficient, the preparation cost is low, and environment compatibility is good.This microbicide compositions is different from existing other microbicide compositions, can suspension of pesticide resistance generation, reach the purpose of agricultural production and income and food safety production.
Thifluzamide of the present invention and own azoles alcohol novel built agricultural chemicals, low toxicity, low-residual, fungicidal spectrum are wide, and control efficiency is good, and the control cost is low, is to prevent and treat the comparatively desirable low toxicity highly effective pesticide kind of rice disease.The formulation that this microbicide compositions is made
